10.5x8mm to 13x10.5mm Dark Hydrangea Large Hole Freshwater Pearls exhibit a high luster with a consistent smooth nacre quality showing very slight irregularities on the asymmetrical baroque shaped bodies. These color treated 2.5mm drill hole freshwater pearls have been produced with a 5 step process to insure a clean and consistent diameter throughout each pearl. Pearl measurements are described as length by diameter.
